1. Called from $wgExtensionFunctions array when initialising extensions

function wfSetupFileSync() { global $wgFileSync; $wgFileSync = new FileSync(); }

1. Needed in MediaWiki >1.8.0 for magic word hooks to work properly

function wfFileSyncLanguageGetMagic(&$magicWords,$langCode = 0) { global $wgFileSyncMagic; $magicWords[$wgFileSyncMagic] = array(0,$wgFileSyncMagic); return true; } ?>
